FLYING MACHINE.

Application led .Tune 26,

To all whom zt may Comer/L Be vit.known that I, GEORGE E. Moin, a subject of the King of Great Britain, residing at Campbellton, Province of New Brunswick, Canada, have invented certain new and uselful ,Improvements in Flyin Machines; and I do hereby declare ,that t e following is a full,clear, and exact description off the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

n The present invention relates to flying niachines. and has for its particular object to provide a flying machine that will rise vertically, fiy horizontally or obliquely, land on uneven ground or remain stationary in midair, and, of which the vertical descent may be effected and controlled with equal facility.

Another object of this invention is to provide an air-craft, capable of vertical ascent,

descent and hovering in flight, which may be operated either by gasoline or electric motors. v

A further object of the invention .is to provide a flying machine whose wind-thrust is equal at any radius ofits propeller, which may be steered by a steerlng plane of a breadth suflicient to engage the wind-thrust clear across its current, whichis adjustable in pitch at either end to cause veering, and at both ends to cause the wind-thrust to lift the rear of said machine to a nearly horizontal position for a direct voyage course.

A still furthe-r object of the invention is to provide a flying machine in which the driving shafts, revolving one within the other, are automatically lubricated, at all their bearings by their own motion, which governs the ilow of oil relatively to their speed, and, the same oil adapted to be'received'over and over again into an voil chamber for circulation.-

Another ob'ect olf the same invention is to provide a ying. machine having a single steering element, whose plurality of meinbers are manipulated from one center for all purposes, and, are so ldesigned, lconstructed and arranged as to automatically guide the machine gently in its downward motion in case of faint, collapse or failure of the pilot.

Another object of the invention is to pro- Specication of Letters Patent.

vide an air-craft, capable df vertical flight, having varying pitch of propeller blades.

With the above and other objects in view which may appear as the description continues or which may otherwise be inherently related with the scope and nature of this invention, the latter consists in details of construction and in arrangement of combination of parts as illustrated in the hereunto annexeddrawings, with which the present specification is co laterally related.

Reference is now to -be had to the said accomp-anyin drawings, wherein like characters of re erence denoting corresponding parts in the several views thereof, are designated for identification purposes by similar reference characters throughout this description.

- of propeller y so bearings through its bearing into its casing tube.

The cross-tree 27 is secured to each` of the shafts 14 and 15, at equal distances below the propeller hubs, and, is calculated to bear most of the strain of the propeller blades through stays running from its extremities to the several sections of the blades. These blades are formed with a gradually increasing width from their points to of their length inwardly, and,

with gradual pitch, viz., from one inch tov five at their points, to one inch to three at half radius and two inches to one at the base of the propeller, their shape is so designed as to give the same Wind-thrust, although one propeller is revolved to the right and the other to the left. j

The telescope shafts 14 and 15, upon which the propellers 1 and 2 are respectively mounted, are secured to 'the bevel gears 22 and 23 adapted to mesh with pinions 30 and 31, oppositely disposed, which are separately secured to the two motor axles 25 The solid bearing 32, fitted against and secured to the interior of the case or housing 16, and, holding a double set of ballbearings, cones and cups 33, serves as a support for the tube shaft 15 and the gear 23 rigidly mounted thereon. The inner shaft 14, having its end journalled within a solid bearing 34 formed with the casing, serves also as a supporting means for the latter.

About three inches tothe right of these the tubular shaft 15 is formed with perforations 35 and 36 through which the oil from the'oil chamber is admitted to the spiral grooving 21 formed on the periphery of 'the inner shaft'14 and extending to the upper end of shaft 15. The motion of this shaft 14 being to the left, the oil is forced upward, as an auger, to a skimmer cup 18, which is screwed on the extremity of shaft 15, and through which shaft 14 is al- The joint between said shaft and said cup is effectively fitted with suitable packing.

Secured to this cup 18 is an oil tube 19, about inches in diameter, affording a passage for the oil, down through the hub 2, through itsflanges 26 'and cross-tree 27, from where said oil is discharged into a similar cup 17 and packing shaft 15 which is similarly adring 56 on 16 serving as a bearing for justed` to casing v, same. -The said shaft 15 is provided with spiral grooving 2O suited to force the oil innesco down through casing' 16, which acts as a bearing, intothe bul'ged out portion of saidl tion curving upwardly and oppositely to said projection 29, engages with the latter both ends of a slide bar 11, substantially parallel with the propeller shaft. This arrangement is effected on both lateral sides of the motor 10. A pulley 40 is mounted at each end of these slides 11, and with the two pulleys 38 and 39, one on each side, the adjustment of the steering cables 6 and 7, is provided for. The said steering cables 6 an 7 are secured with a winding to the steering drums 8 and 9 to the sliding heads 4. The drum. 8 has connection with a tube which is secured to a steering wheel 13. A bearing 50 located between drum 8 and wheel 13', is secured to side braces from thecasing below and forms a bearing for the inner shaft engaging the upper steering wheel 13 and lower drum 9, resting in a bearing on the casing beneath.

The lower steering wheel 13 is allowed end-play so that it can be gripped by hand separately without interference with the otherwheel 13, or' raised and gripped with said upper wheel 13 when so required.

A key is adapted to enter a 4ratchet on lower wheel ferrule for the .purpose of locking it to the inner shaft at any oint.

After locking said steering vieelsv they are still adapted to be moved to the right or left. If moved to the right it will increase equal pitch on the whole plane, and if moved. to the left, will decrease pitch equallyl on same. tained fthe desired altitude, these may be locked during the whole voyage, as all veering is overcome at the time of locking and the machine at voyage speed can only vary upward and downward 'and this is governed by turning steering wheels 13 and 13 to right and left. l

When it is required to change the course to .a right angle, operator should turn wheels 13 and 13 together to the left, then releasev angle, the wheels 13 and 13 are to be l vso Once the machine .has athinged to the sliding -heads 4, and their.y

upper ends, .at their junction with the plane arestayed to the top end `of tubular casing or bearing 16 by means of steel cables 51, thereby hmging and aociating the steering plane with the play of the steering device. In furtherance of same, provision is also made to the effect that, in case there is failure on the part of the engine or power, the whole plane will glide forward till it reaches the tubular casing and will then still'serve to effect the safe landing of the machine right side up.l

A seat 12 hinged to the motor top heads has an extension on its base from either side of same. This extension is engaged by a cable 48 connecting it with the adjustment -of road wheel 49, thereby causing the said seat to be automatically adjusted level;

A levelling wheel 55, secured to bearing-50 with a worm gear and drum, serves the pur. pose of raising and lowering front road wheel 49 which is hinged to the motor base by arms 52 and to the upper casing by arms 53 and 54. l

A wind-shield 41 is mounted on motors 10 and casing 16 and one pneumatic road wheel is adjustably mounted in front, while the two rear feet or rests are stationary.

The aggregate surface of all four blades of the herein referred' to propellers forms in total 30 square feet, while the steering plane has a surface of 32 feet.

Referring now more particularly to the illustration embodied in Figure 1, the latter clearly shows a steering element and its plurality of members. As shown these are in a pOsition to cause veering to the right, which is effected by having increased pitch 'to the right, whereby a steering cable, connecting by means of pulley blocks, the drum of this wheel to the sliding arm, as drawn forward the right .arm 5, and, this arm being stayed to the plane changes its pitch accordingly: turn to the left to veer to the left. Whenthe desired elevation is attained by the machine, with the destination point in front of same, and no veering evident, both steering wheels are locked together, and turned to the right, thus increasing the pitch equally on both sides and accordingly lifting the rear to the desired position or nearly horizontal. It is obvious that in this position all the Weight is borne b the steering plane, and power must be re uced or the machine will attain terrific speed. Thus 80% of the power, propeller speed and fuel, may be utilized economically for long flights. l

In Figure 2 where the machine is shown in a nearly horizontal position, is' also clearly shown an action ofthe steering plane in relation with the arms 5 .adapted to be oscillated backward and forward on its slides 4, and, the steering element.

For the purpose of causing a curving course of the flyin machine when the steering 'wheels are loc edfor horizontal flight, without altering the pitch of either end of the steering plane, a steering rudder and tiller 57 is provided for which is pi'votally secured to the motor case 10 by means of bracket bearin 58. This contrivance is lo cated sufficient y to the left of the road wheel Upon the respective hub portions of thepropellers, circular solenoids 1', 2', 3', 4', 5', 6', 7' and 8' are arranged, and with energization, the magnetic flux created thereby will effect rotation of the same in opposite directions, as is the case with the well known type of rotary electric motors. Thus, it will be appreciated that motive means for the respective propellers are arranged directly upon their hub portions and in consequence, the use of gearing or kindred connections for' transmitting motion to the propellers and by consequence, increasing friction as well as decreasing the speed efliciency of the propellers will be eliminated.

The numeral designations in this Figure 7 are to be described as follows: Numeral 60.

hile I have described and illustrated one form of carrying my invention into practice, it is, however, understood that various changes in the detalls of construction and the arrangement of parts may be resorted to, without departing from the spirit of the invention as set forth in the following claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent isz- 1. In a vertical flying machine, the conibination of two propellers adapted to revolvein opposite direction to each other, the said 'propellers providedwith a plurality of blades, said blades having a pitch designed to give windsthrust in the same rearward direction and having .their surfaces adually increasing from their extreme points to one half of their length inwardly, thesaid pitch of same gradually increasing from one inch to five at their points to one inch to three at half radius and two inches toA one,

In a vertically ascendin and' descending iying machlne, a mu tiple-steering plane adapted to engage the wind-thrust of said machine clear across its current, means for .changing the pitch of said plane at either of its ends to cause veering and at both ends equally to lift the rear to a subas described and for the purpose stantially horizontal position, thus causing it to assume the function of a monoplane.

3. In a vertically ascending and descending iying machine, a multiple steering- 'connected to said struts for oscillatin plane adapted to engage the wind-thrust of said machine clear across its current, a separate operating wheel drum and cable provided for changing its pitch at either end t-o cause veering, said wheel drums adapted to be locked together for the purpose of thereby arresting all Veering, the said wheels when locked together adapted to be handled asa single wheel for the purpose of guiding the machine in flight horizontally, substantially as described and for the purpose specified.

a plurality of telescoped lubricating journals for said motor elements, a steering plane arranged above the propellers in a manner to engage the wind-thrust entirely across its current, struts for supporting said steering plane hingedly and slidably connected to the fuselage of the machine, meas t e same individually or collectively and either forwardly or backwardly, and adjustable carriage means secured to the machine fuselage'adapted -topermit the same to traverse an uneven terraine surface.

5. In a flying machine, the combination of a pair ofV oppositely rotatable propellers, the blade surface of said propellers increasing inwardly in width and pitch, and reversely rotating motor elements secured to the hub portions of said propellers and adapted to inter-function as and for the purpose set forth.

6. In a vertical flying machine, the combination ofrv oppositely driven direct-thrust twin propellersthe pitch of the blades of same gradually increasing from their points to the centre of said twin-propellers, said propellers being provided with magnets in each hub,serving as a motor, the said blades reinforced by steel stays, said twin-propel 1ers mounted on a self-oiling oppositely driven telescoped twin-shaft.

7. Ina flying machine, a duplex oppositely driven direct-thrust twin-propeller, whose pitch of blades gradually increase from theirpoints to propeller centre and are v reinforced by steel stays engaging cross trees beneath, magnets in each hub of said propellers adapted to serve as a motor, said propellersv mounted on self-oiling oppositely driven telescoped twin-shafts, whose inner member is projecting at both ends and is made with spiral grooves to force oil upwards to a skimmer cup from where it is carried to propeller and connections, an oil tube secured to said skimmer cup and leading through the hubs of. said propellers on the outer member to which the cup and tube are secured to the casing tube and through which the' outer member projects for propeller connections. i

In witness whereof I have hereunto set my hand.
